Introduced in 1990 the Endura was the first of its kind on the market and it opened up the knife market to lightweight performance, one-hand open pocketknives that just about everyone could afford. The Endura settled as one of Spyderco's top two bestsellers and the improvement hasn't slowed since.
Refinement has been so ongoing and continual Spyderco tagged the updating/upgrading process with the term CQI- Constant Quality Improvement. During the Endura's CQI journey Spyderco tweaked ergonomics, refined blade steels and fine-tuned its performance countless of times. It is an evolutionary work in progress and the next level is here with the new Endura4. The model now has screw construction making cleaning and adjusting easier.
The 3-3/4" VG-10 blade is coated with a non-reflective titanium carbonitride and is flat saber-ground with a stronger tip and a hardness at 60-62 Rc. Black fiberglass reinforced nylon handles come molded with Bi-Directional Texturing® for preferred traction and improved ergonomics. Phosphor bronze washers smooth out the open/close action and the clip is upgraded to a four-way tip-up, tip-down, left- or right-handed clip. Closed length is 4-7/8", weighs 3.6 oz. Made in Japan. Suggested Retail $129.95.
